Ll FTiNG-JACK.

SPECIFICATION forming part of Letters Patent No, 348,480, dated August31, 1886.

Application filed May 8, 1886. Serial No. 201.567.

To all whom it may concern.-

Be it known that I, AnDIsoN SoUDERs, a citizen of the United States, anda resident of Greentown, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in \Vagon-Jacks; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification,and in which Fignrel is aside view of my improved wagonjack, showing itraised. Fig. 2 is similar view showing it lowered, and Fig. 3 is a sideview showing portions broken away.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of wagon-jacks in which a barhaving a rest for the axle has the end of a lever pivoted to it, thesaid lever having its fulcrum upon the upper ends of arms pivoted attheir lower ends to the standard; and it consists in the improvedconstruction and combination of parts of the same, as hereinafter morefully described and claimed.

In the accompanying drawings, the letter A indicates the standard, whichis provided with a suitable base, B, and which is provided at one sidewith guide bails or staples C C, in which the lifting-bar D slides. Thisbar is provided at its upper end with a forwardlyprojecting rest, E,upon which the axle of the vehicle may rest, and with tworearwardlyprojecting lips, 1*, having transverse perfora tions in theirends. The inner end of a curved lever, G, is pivoted upon a bolt, 11,passing through the perforations of the lever, and this lever isfulcrumed near the inner end upon a belt, I, passing through the upperends of two arms, J, connected at their lower ends by means of a bolt,K. A plate, L, is secured to the side of the standard, and projects withits rear edge beyond the rear edge of the standard, and has notches M inthe said edge, of sufficient depth to receive the bolt connecting theends of the arms supporting the lever. A

(No model.)

latch-lever, N, is pivoted at its upper end to the upperend of the rearedge of the notched plate,and bears against the said notched edge,covering the notches, and the lower end of this latch-lever is curved,and may engage a bolt, 0, upon the side of the standard, the leverserving to keep the bolt connecting the arms within the notch in whichit has been placed. lVhen the lifting-bar is lowered, the curved leveris tilted upward and the arms swing outward, and when the outer end ofthe lever is depressed the lifting-bar will be raised and the arms willswing inward until the fulcrum of the lever is forward of the point ofattachment for the inner end of the lever, so that the weight upon thelever will force the free end of the lever forward, causing it to bearagainst the rear side of the standard.

The lifting-bar maybe raised or lowered to suit the different heights ofvehicle axles by adjusting the pin of the fulcrunrarms in a higher orlower notch, and the said bolt may be prevented from slipping out of thenotch, after it has been adjusted in the same, by the latch-lever, whichmay be locked down against the edge of the plate, closing all thenotches.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. In a lifting-jack, thecombination of a standard having vertical guides, a lifting-bar having asuitable rest and sliding in the guides, and havingrearward]y-projecting lips, two arms pivoted at their lower ends to therear edge of thestandard, and a curved lever having its inner endpivoted between the lips of the lifting-bar,and having its fulcrum nearthe inner end between the upper ends of the arms, as and for the purposeshown and set forth.

2. In a lifting-jack, the combination of a standard having suitableVertical guides upon its side, and having a rearWardly-projecting plateor flange formed with a series of horizontal notches, a bar sliding inthe guides and having a forwardly-projecting rest andrearwardly-projecting lips at the upper end, two arms having their lowerends connected by a bolt, and having the said bolt resting in one of thenotches, a curved leverhaving its inner end pivoted between the lips ofthe bar, and I In testimony that I claim the foregoing as having itsfulcrum near the inner end between my own I have hereunto affixed mysignature the upper ends of the arms, and a latch-lever in presence oftwo witnesses.

pivoted at the upper end of the notched edge ADDISON SOUDERS. 5 andhaving its straight portion closing the XVitnesses:

notches, and its lower end secured by a stud, LEONARD RARE-R, as and forthe purpose shown and set forth. I
